I have this set in hard copy and have used it for many decades. It has superior content for Bible study (and much more). As a simple example, see the subject entry for "Well" (volume 10, pages 903-905). As a Logos product the abundant Scripture references ought to be readily accessible. There are extensive bibliographies for most subject entries, Biblical, historical, theological, biographical. I am thankful a similar product which I also have in hard copy, The New Schaff-Herzog Encyclopedia of Religious Knowledge, has recently moved into production. I look forward to its release in Logos. But over the years, I have found McClintock & Strong's Cyclopedia of Biblical, Theological, & Ecclesiastical Literature to be more than equally useful. For the Community Price, you cannot beat the value for such a valuable resource. I eagerly await receiving this resource in Logos. Take a look at the product in Community Pricing.
